Bug description

A bash script with this line, called by crom 15 min after each equal hour makes one, sometimes two coredumps.
Problem introduced end of October, start of November 2025. Did not make any problems for more than 3 years before.
The line:
gsettings set org.cinnamon.desktop.background picture-uri "" && gsettings set org.cinnamon.desktop.background picture-uri "file://$wdir/back.tif"
(Background is changed to a new picture of the moon)
This works, but coredump(s) is/are produced.

The second coredump my be generated if screensaver is running in the time the script is started.

Problem occurs also by starting the script trough a starter.
I does NOT occur, when the script is started by auto start at boot time.
But it OCCURS, when I go to system settings/auto start/MOON--> run now.
